Message circulating in social networks alerts to ‘law of a minute and a half’. Doctors say that blood pressure may fluctuate, but risk does not exist.
Does the person who suddenly wake up to urinate and get up quickly from the bed can suffer a stroke if they do not respect the ‘law of a minute and a half’? It is not true.
A text with this information circulates on the internet. He recommends that people who wake up at night to go to the bathroom respect the law of a minute and a half to avoid the risk of death.
G1 heard the Director of Cardiovascular Health Promotion of the Brazilian Society of Cardiology (SBC), Weimar Sebba Barroso, and the coordinator of Training in Cardiovascular Emergencies of the same institution, Sérgio Timerman. They claim that although a person may experience dizziness on standing up, there is no risk of stroke or life-threatening because of it.
“There is no law of the minute and a half. What happens often is that the person lying down for a long time (it is not necessary to be sleeping or not) can present a lipothymia, that is, a pressure drop that can often be even physiological , but that in the older people can cause dizziness.This dizziness can cause a fall of the height itself, but there is no such thing as a minute and a half, “says Timerman.
Barroso also says that at night there is a tendency for the blood pressure to stay a little lower, even for being a moment of rest. When this person suddenly rises, there may actually be a drop in pressure, a decrease in blood flow to the brain, and this can lead to syncope, a sudden loss of consciousness. In this case, there may be a fall to the ground, but there is no association to the occurrence of a stroke.
“Actually, the risk of a syncope or a pre-syncope when getting up to go to the bathroom at dawn does exist, especially in older people. It is important to wake up, sit first, wait a little, and then get up and get up we tend to do this orientation very often to our older patients, “he says.
However, the doctor makes it clear that there is no risk of sudden death. “What happens in a situation like this is that – and that’s where the truth is – there is a fall to the ground and the person can get hurt. But when it falls (without serious injury) there is a reestablishment of the cerebral blood flow and it does not increase the risk of sudden death or stroke.The truth is at risk of fainting, but there is no truth in the information of increased risk of death or stroke, “he says.
